Summary
CVE-2024-5947 is a medium-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Deepseaelectronics Dse855 Firmware. Its CVSS base score is 6.5 (Medium).
Operationally, ranked in the top 1.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
This vulnerability is a missing authentication issue in the web-based UI of Deep Sea Electronics DSE855 devices, tracked as ZDI-CAN-22679. It enables unauthenticated access to configuration backup functionality, resulting in disclosure of stored credentials. The flaw is rated CVSS 6.5 with an attack vector of network-adjacent and carries the CWE-306 classification for missing authentication.
Network-adjacent attackers can exploit the issue without credentials or user interaction to retrieve sensitive configuration data. Successful exploitation yields stored credentials that can be used for further compromise of the affected device or connected systems.
The associated EPSS score rose from a low baseline to a peak of 0.8546 on 2025-12-11 before receding to the current value of 0.7404, indicating emerging exploitation interest after public disclosure. No information is provided on patches or mitigation steps from the referenced ZDI advisories.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
